WebSubtraction as the addition of the opposite. Another way scalar multiplication relates to addition and subtraction is by thinking about \bold A-\bold B A −B as \bold A+ (-\bold B) A+(−B), which is in turn the same as \bold A+ (-1)\cdot\bold B A +(−1)⋅B. This is similar to how we can think about subtraction of two real numbers! WebSep 16, 2024 · Theorem 3.2. 1: Switching Rows. Let A be an n × n matrix and let B be a matrix which results from switching two rows of A. Then det ( B) = − det ( A). When we switch two rows of a matrix, the determinant is multiplied by − 1.
